Their efforts helped create the National Park and National Forest systems in the U.S.; and through the Global ReLeaf program, American Forests plants millions of trees each year and advocates the benefits of both rural and urban trees, good science, and sound policy.

On April 22, 1970, the first Earth Day kicked off the modern environmental movement as the nation dedicated itself to focusing on environmental issues. Then about 20 million Americans expressed their concerns for our environment —and now about 1 billion will acknowledge its 41st anniversary globally.
